We understand that not everyone wants or can pay for the “add audio feature” of the app. So we’ve created an alternative to allow the chance to add audio for free. This is through watching an ad.
When you go to add audio, there is an option to watch an ad that will, as a reward, give you the option to add your own sound to the animation.
That part of the process is not controlled by us - it is controlled by our ad providers. It is possible that at times there are no available ads to be watched. If that happens, wait some time and then try again.
